Based on atomic mass
Explanation:
Elements were arranged on the first periodic table based on their atomic masses. 
The mass of an atom is made up of the mass of the nucleus which contains the protons and neutrons. 
- Dimitri Mendeleev was the first person credited for arranging elements periodically. 
- He was said to have been inspired while playing his game of solitaire on a train. 
- On his table, he left spaces for the atomic masses of elements not yet discovered. 
- Today, the periodic table is based on the atomic numbers of elements. This is the number of protons in an atom.

Answer:
4.48 grams is the mass of potassium hydroxide that the chemist must weigh out in the second step.
Explanation:
The pH of the solution = 13.00
pH + pOH = 14
pOH = 14 - pH = 14 - 13.00 = 1.00 
![pOH=-\log[OH^-]](https://tex.z-dn.net/?f=pOH%3D-%5Clog%5BOH%5E-%5D)
![1.00=-\log[OH^-]](https://tex.z-dn.net/?f=1.00%3D-%5Clog%5BOH%5E-%5D)
![[OH^-]=10^{-1.00} M=0.100 M](https://tex.z-dn.net/?f=%5BOH%5E-%5D%3D10%5E%7B-1.00%7D%20M%3D0.100%20M)

![[KOH]=[OH^-]=[K^+]=0.100 M](https://tex.z-dn.net/?f=%5BKOH%5D%3D%5BOH%5E-%5D%3D%5BK%5E%2B%5D%3D0.100%20M)
Molariy of the KOH = 0.100 M
Volume of the KOH solution = 800 mL= 0.800 L
1 mL = 0.001 L
Moles of KOH = n


n = 0.0800 mol
Mass of 0.0800 moles of KOH :
0.0800 mol × 56 g/mol = 4.48 g
4.48 grams is the mass of potassium hydroxide that the chemist must weigh out in the second step.
 
        
             
        
        
        
An atom is the smallest particle that can have the properties of a compound.
